Do tounge rings actually feel that amazing for guy when receving oral?

My bf ex girlfreind had a toungue ring and gave him head.. he says i am absoulutly by far the best especially beacuse i am his first love.. (We dated befor this tramp to! just were having problems and he ended up with her for a little while but now were back together!) is he lying does it really feel that good that i cant match up or is it possible to do as good as a job without a tounge ring?
